#### Steeper, Faster, Division, and Slope

What does "steeper" mean? What does "faster" mean? And how do these ideas connect to the idea of linear functions? This 3-part series explores these questions and helps students to understand why we divide when computing slope and what proportional correspondence has to do with it all!

#### Sharing Pencils

Sarah and Michelle are working on a class project using colored pencils. Given some information about the number of pencils that Sarah and Michelle had when they started, and how some sharing of pencils has taken place, students must employ proportional reasoning skills to determine how many colored pencils the girls now possess.

#### 2015 Excellence in Mathematics Contest

This is the Team Project from the 2015 Junior High Excellence in Mathematics Contest at Chandler-Gilbert Community College. It involves lots of open ended problems from many mathematical areas: Find the weight of a snowman (geometry, proportional reasoning) Find how long it takes ice to form on a lake (rate of change, awkward units) Questions about the amount of mining done in Northern Minnesota (proportional reasoning, conversions) You can use just one part or all parts depending on the audience and the purpose.
